MECHANICAL MOVEMENT.

'ments, of which the following a specification.

This invention relates to an improvement in mechanical movements, havingreference especially to means for converting continuous rotary intointermittent rotary motion and for required for severing the cardboardas fed by-the feed-rollers of match box-shuck makpets and the drivenelement is provided withing machines, and for other purposes.

The object of the invention is to provide a mechanical movement of thecharacter mentioned which shall be simple and durable in constructionand uniform and positive inoperation, and which shall be free fromabrupt jarring blows during the starting moments.

My invention comprises rotary drlvmg and driven elements, whereof thedriving element is provided with a plurality of tapa plurality of radialchannels having arouated entrance-portions which are coordinated withthe tappets, as will be hereinafter described and claimed.

In the drawings-Figure 1 is a side elevation of a mechanical movementembodying my invention, the same being represented as appliedto-feed-rollers, and the elements being illustrated in the relativepositions which they occupy at the instant of locking the drivenelement. Fig. 2 is a side elevation of the elements, showin the. drivingelement slightly advanced W ile the driven element remains locked. Fig.3 is a similar view showing'the action of a tappet stud upon a channelof the driven element to impel the latter. Fig. 4 is a plan of Fig. 2.l0 designates the continuously rotating driving element and 11theintermittently rotatable driven element of my improved movement. Inthe present instance the two elements are in the form of spur wheels,the driving element bein in mesh with a driving pinion 12 and the grivenelement being in mesh with one of the pinions 13 of a palr offeed-rollers 14. The shafts of the two spur Wheels are designated 15 and16, respectively.

rounded as indicated at 18.

.The wheel 10 is mounted laterally of the wheel 11, and is prov ded onits inner 'face with a plurality of pro eeting tappets 19, comprisingstuds or rollers-1n the present instance three. The tappets areequallyspaced apart at points equidistant from the center of the adjawheel 10,the spaced relation of the tappets to each other and to the radialchannels of the wheel 11 being, such .that the tappets enter the saidchannels in successive order, move along the same toward the center ofthe wheel and then recede therefrom, and that as the approaches themouth of the channel with which it is engaged the succeeding tappetenters the mouth of the next following channel, and so on.-

The curvature of the outer ends of the channels is such thatwhen theelements are in the relative positions represented in Figs. 1 and 2 theinner walls of the mouths of the two lower channels are concentric tothe wheel 10, that is, such walls comprise corresponding arcs describedfrom the'center of the Wheel. Hence when both tappets register with andmove on the proximate arouated portions of the channels no motion istransmitted from the continuously rotating driving to the drivenelement, but on the contrary the latteris temporarily locked againstrotation; yet the instant the rearward tappet escapes the mouth of theproximate channel the leading tappet contacts with and rides upon theopposing radial Wall of its channel, progressively entering the latter,as seen in Fig. 3, and then receding therefrom. The three tappets of thedriving element during its continuous rotation thus act in successiveorder upon the walls of the radial channels of the driven element andthereby intermittently rotate the latter, and positively lock it duringthe intervals of rest. Owing tothe relation of the tappets of thedriving element to the channels of the active tappet in a recedingmotion driven element whereby two tappets co-act concurrently with thearcuated portions of two channels during each interval of rest, not onlyis an efiective lockin of the driven element insured but the a ru tstarting blows inherent in an ordinary eneva stop motion are avoided.

I claim Mechanism of the character described comprising two rotatablemembers mounted in lateral relation to each other, one of said membersconstituting a driven element having a series of corresponding radialchannels with flaring arcuate portions at their outer ends, and theothermembenconstituting a driving element having a serles of tap- Cplotsequally spaced apart at points equl istafit from its center and adaptedto coact successively with the walls of the said channels and impart tothe driven element an intermittent rotary motion, two of the said tapets concurrently contacting with and r1 mg upon the adjacent arcuateportions of the two channels at the end of eachimpulsepf the drivenelement,-the walls of sald ad acent arcuate portions com risingcorresponding arcs described from t e center of the driving element witha radius equal to the radial distance of the inner face of the tappetsfrom said center.
